The photo shows tall trees at the north and south sides of the house.
When mounting a antenna in a tree , cut tree branches away so that branches can not whip around disturb reception and can not whip around and break the antenna/s.
Here are 2 VERY STRONG ANTENNAS that are good for tree mounting.
Aim the antennas to the north.
The C5 comes with a coax coupler combiner that connects VHF C5 antenna and UHF CS2 antenna.
